This trial is testing a new approach to treating prostate cancer using a single, highly focused radiation dose delivered in one session. Instead of the traditional approach of multiple treatments over several weeks, this study uses advanced radiation technology to give a very high dose of radiation all at once, aimed precisely at the prostate. Researchers want to see if this single-session approach can work safely and effectively for men with early-stage prostate cancer.
Standard prostate cancer radiation treatment usually requires many sessions spread over weeks. This trial exists to find out whether a single, powerful radiation session might work just as well while being more convenient for patients and reducing the time spent in treatment.

You would have three main visits. First, a brief procedure to inject a protective gel between your prostate and rectum (similar to a prostate biopsy). About a week later, you'd have CT and MRI scans to plan your exact treatment. Finally, you'd return for the actual radiation treatment, which lasts about 30 minutes. A catheter will be placed in your bladder before and removed after the scans and treatment. The entire process takes about two weeks from start to finish.
